ANTI-LOCK BRAKE SYSTEM (ABS)
ABS
H: G SENSOR
The G sensor detects changes in the vehicle's acceleration/deceleration rate in the longitudinal
direction.
The moving electrode of a capacitor in the sensor moves away from or close to the fixed electrode
as the vehicle accelerates or decelerates and the resulting change in the capacitance of the ca-
pacitor is outputs to the ABSCM as a change in the voltage.
